This invention relates to loading-apparatus 'andmore particularly to a-floor engaging guide for: the-oscillatory loading head of a' mobile load ing machine. i In a loading machine of the type disclosed in my Patent No. 2,234,07Lgranted March 4,1941,

some difficulty was encountered in properly po- .sitioning the vertically swingable, oscillatory loading flhead or. vibratory gatherer of the machine; and. at timesthe head or gatherer would be carried too high with respect to the bottom during the loading operation and at other times the head would be too low, resulting in undesired diggingof its forward penetrating portion into the bottom.. {The present invention contemplates improvements over myearlier machine in that anyimproved floor. engaging guide is provided-for the vertically ti1tab1e,.oscil1atory loading header vibratory gatherer sothat the forward penetrat ing edge of the. head may be always properly positionedwith respect tothe bottomwhen .It-isaccordingly a primary object of the presimproved .mobile Another object. is. to provide an improved supporting. ering portio'noffla vibratory gathering head whereby undesired diggingof. the gathering portion into the .bottom is. substantially. prevented.

The loading machine generally comprisesa mobile base I having a frame 2 mounted on conventional crawler'treads 3 whichmay be driven and controlled to effect propulsion'and-steerin ofthe machine in a well-known mannen. Carried above the base frame is avibratory ores.- cillatory gathering and elevating. head thaving, as shown in Fig. 1,. a relatively wide frontgathering head portion 5 and a relatively narrow troughlike portion 5 extending rearwardly of the widened portion, and arranged to gather and elevate the material to be loaded and to discharge the material rearwardlyof the machine. The frontiwidenedgathering head portion 5 has a serrated front penetrating edge 1, and is formed with forwardly'diverging sidewalls 8 whichconverge into the parallel longitudinal sidewallss9.

of; the base frame 2 .to swing in avertical plane with respect-to the base and apair of upright Y extensible hydraulic jacks l5 are arranged at the opposite-sides 0f the forward portion of the base frame'andfare pivotally connected at their lower ends at It to the base frame and pivotally connected at their upper ends at lltothe upper portion of the tiltable frame it. By supplying liquid under pressure to-the cylinders of these jacks the tiltable frame together. with theloading-head may be swung upwardly about the pivot I i with respect to the base, and when liquid is vented from the cylinders of these jacks the frame and loading head may be swung downwardly.- By trapping liquid within'the jack cylinders" the tiltable frame and the loading head may be locked in adjusted position. The upper tiltable frame i!) has suitable curved guides i8 slidably engaging arcuate guideways 3.19 on the forward portion of the base frame for guiding I and which are secured. to crank arms 21, the

latter in turn being pivotally connected at 28 to links 29. The links 29 are pivotally connected at 30 to arms 3| integral with the front hanger links I l. Thus, when the eccentrics 23 are driven by the motor 2|, the gathering and elevating head 4 is rapidly oscillated back and forth or vibrated on its arm and link mountings, in the manner fully described in my copending application Serial No. 788,703 mentioned above, to effect gathering and loading of the loose material on the floor.

In this improved construction, to prevent the; front penetrating edge 1 cf the widened front portion of the head from digging into the bottom during the loading operation, the forward part of the frame [0 has forward side projections 32 extending forwardly and outwardly beneath the head and provided with bottom floor engaging shoes 33, and with upper guide portions 34 engaging the straight outer sides 35 of the forward widened portion of the head for guiding the latter during its oscillation or vibratory motion. These floor engaging shoes 33 serve to prevent the penetrating edge of the head from running into the fioor in the lowered position of the head, as shown in Fig. 2 and at all times adequately support the head in its proper position with respect to the fioor during the gathering and loading operation.

The loading machine may be propelled about the mine and maneuvered with respect to the work by the crawler treads 3 in a well-known manner. .'During transport, the forward ends of the gathering and elevating head 4 and the tiltable upper frame It are held raised above the floor level by the hydraulic jacks i5, and when the working place is reached, the jacks may be operated to lower the frame shoes 33 into contact with the floor to bring the penetrating edge I of the head into close adjacency with the floor. The

motor 25 may then be operated to impart, through the arms and links, a rapid oscillatory or vibratory motion to the head in a direction generally lengthwise thereof, and, concurrently, the crawler treads may be operated to advance the head into the material to be loaded, to feed the widened front head portion 5 beneath the loose material. As the head is rapidly oscillated or vibrated, the loose material is gathered thereon and moved rearwardly and upwardly along the trough portion 5 to discharge at the elevated rear end of the latter, all in the manner fully disclosed in my above mentioned copending application.

quately to guide the forward portion of the head during its operation. Other manners of use and advantages of the invention will be clearly apparent to those skilled in the art.

Thus, the gathering and elevating head rapidly and continuously gathers and conveys the mate rial, and the material moves in a substantially steady stream rearwardly and upwardly along the trough to discharge. The forward guiding portions on the tiltable upper frame with its shoes 33 slidingly engaging the floor provide adequate guides for the vibrating head and serve to prevent digging of the forward penetrating edge of the head into the floor or bottom.

As a result of this invention, an improved loading apparatus is provided wherein the vibratory loading head of the machine is adequately supported and guided during the gathering and loading operation. By the provision of the shoes and guides on the frame projections beneath the vibratory head the penetrating edge of the latter is prevented from inadvertently digging into the floor when in lowered position, and serve ade- While there is in this application specifically described one form which the invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
